  • the economy of meat production is significantly influenced by the extent of utilization of the fodder used for feeding the animals, i.e. the amount of fodder required to achieve a certain weight gain. Another important parameter is the period during which the animals reach the desired marketing weight. The lower the fodder amount required and the shorter the time of feeding required to achieve the slaughter weight, the more economical is the meat production.
  • insulin administration for as short period as about seven days at a cumulative amount of less than 2 IU per chick suffices to exert the beneficial effect of insulin on the young poultry intestine.
  • Insulin administration should start a short time after hatching, from immediately after hatching to 2-3 days post hatching. According to certain currently preferred embodiments, insulin administration starts on the first day after hatching. As disclosed in the example section hereinbelow, such insulin administration results in an increase in weight gain of treated animals compared to non-treated animals up to the poultry marketing day.
  • Shortening the insulin administration time period is of significant importance for the poultry industry. There is a growing awareness of the regulatory authorities as well as the public regarding consumption of food containing potentially health-hazardous compounds. Accordingly, fresh meat which is free of traces of growth promoters has higher economical value.
  • the disclosure of the present invention provides for a significant weight gain up to the marketing day while insulin administration is ceased well before this day, such that no traces of exogenous insulin may be found in the marketed poultry. Taking together the basic low cost of insulin with the short administration time, low insulin amounts required, significant weight gain and no insulin residues at marketing, use of insulin as a growth promoter according to teachings of the present invention is highly advantageous for the poultry industry.
  • the present invention now shows that intact mammalian insulin is highly effective in increasing poultry weight gain. Moreover, the present invention shows for the first time that oral administration of insulin, particularly human insulin, increases the poultry intestinal mass.
  • Insulin is considered as a highly conserved protein when mammalian proteins are compared. For example, bovine and porcine insulin are very similar to human insulin. In terms of amino acid sequence, seven amino acids differences are detected when avian insulin and human insulin are compared.
  • the observed increase in intestinal mass may contribute to the increased weight gain by enhancing the feed conversion efficacy or enhancing the amount or rate of food consumption. It is to be noted that the increase in weight gain not only did not affect the general health and viability of the treated animal negatively, but to the contrary, enhanced it. This is reflected by the increase in breast muscle weight in treated poultry and no change in the percentage of fat.
